Big Bazaar / Futurebazaar / Future Retail / Hometown — Big Bazaar App. UPI Payment!!

I ordered some groceries from the big bazaar app and paid with UPI today i.e. 20/8/21 at 8 o clock in the morning. For the next 1 hrs. the order status was awaiting payment and then after more 30 mins the order got cancelled and there is no refund. My money is now literally stolen by these guys. And when i contacted big bazaar customer care no. They said that my order is cancelled due to non receiving of money and asked me to contact my bank, but everything is fine from my bank's side. When i called them again still they don't want to take the blame on their heads and still asking me to contact my bank. And also for some reason the same order got duplicated for 3 times. They have pathetic service and a idiotic customer care infrastructure and also a garbage app. I repeat don't every buy from their app if you want your money to not to get stuck somewhere or it to get stolen by them.
